That’s true travelling is knowledge. This is the only way by which you can get a chance to meet people around the world. With different lifestyle, religion, the way the see life which teaches us a lot, I remember meeting a couple from spain in India who were both teacher and was on the world tour, and were sharing that how people or cost of leaving in a same country differ or states to states. There are some place in the world were people loves to meet travellers and that’s there mode of happiness.
